GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 412,694, dated october s, 1889.

Application filed May 12, 1887. Serial No. 237,981. (No model.) v'

To all whom it may concern:

Be it knownrthat We, DANIEL KELLOGG BAKER, of Chicago, in the county of Cook and State of Illinois, and CHARLES H. GREEN, of the city, county, and State of New York, as-

signors to the NEW/YORK BRAss COMPANY, a corporation, have-invented a-certain new and useful Improvement in Gas-Burners, (never yet patented in any country g) and we do herero by declare that the following is a full, clear, aud exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention consists in a mechanism so I 5 constructed and arranged as more completely to regulate the pressure and flow and greatly to increase the illuminating-power of gases, Whether natural or manufactured, when used for the production of lightl In the attempts to usefor illuminating purposes thenatu'ralgases it has been found that no ordinary burner produces a satisfactory light. Indeed, the distinguishing characteristie of the combustion of the natural hydrocarbon gases seemsto be the production of intense heat. While they have largely taken the place of coal, coke, and other fuels in the smelting and workingl of metals, and in other processes of the arts and manufactures 3o which require the greatest heat, yet for the purposes of illumination they have usually proved flickering and unsteady, and their combustion, while producing great heat, has usually aiforded very little light.

Our invention is designed to obtain from the combustion of natural gases a light of great illuminating power and of uniform steadiness and brilliancy.

The mechanical part of our invention is 4o vdescribed as follows:

Figure l shows in perspective our completed invention, inclu din g the chiInn ey,which may be longerl or shorter, as may be desirable. Fig. 2`is a central Vertical section of the same. Fig. 3 is a plan view of the device, looking from the top downward. Fig. i is a cross-section .of the same, drawn at the dotted lines N N, Fig. 2. Fig. 5 is a central Vertical section of the cap B. Fig. 6 is an outline of the different parts of the cap last mentioned, showing the diiferent proportions thereof.

Similar letters of reference designate corresponding parts in the several figures.

A is an elongatxl tube fastened at its lower extremity, in the usual manner, to an ordinary gas-pipe, and through which the gas is introduced to the apparatus. It opens into the `funnel-shaped cap B, which tends to regulate and equalize the pressure of the current of gas, while at the same time subjecting it to the heat of the iiame. This cap connects the tubeAWith a tube C, surrounding it, and which conveys the gas from the cap B through two or more hollow projecting arms D D D, fixed in the frame, as shown in Fig. 4, into the reservoir or chamber E E. This reservoir or chamber E E has between its exterior and interior walls wire screens to further regulate and equalize the pressure Iings indicate, so as to increase the steadiness of the flow of gas.

F is the eone,which surrounds the reservoir or chamber E E. It is beveled at the top and perforated at the side or at the side and top. It has on its outer side the shoulder G, on which the chimney rests, and by which it. isin part held in place. It has Within it, at the bottom, the perforated shell or screen H, and at or near its top the perforated screen M, which are designed to admit the air to the flame and regulate the same.

I is the chimney, designed for use in connection with the burner, and which is heldin place by the shoulder G and the exterior gallery K K, as shown in Figs. l and 2.

One or more wire screens L L are placed between the pipe C C and the reservoir or chamber E E, and serve further to regulate the air and the iiame.

What we claim as our invention, and desire to secure by Letters Patent, isv

In a gasburner, the tube C, having the hollow laterally-projecting arms D, the funnelsllaped cap B, secured to the top of the tube C, and the annular reservoir or chamber E, having top perforations, said chamber sur- 5 rounding a portion of the tube C and conimunioating therewith through the medium of the hollow arms D, Combined with the supply-tube A, extending upward Within the tube C and opening into the cap B, Wire screens Io located within the chamberEbetween its top and Jthe points of connection with the arms D, the perforated cone F, surrounding the chamber E, and the perforated screens Hand M, surrounding, respectively, the top and bottom of the chamber E, for the purpose speci- I5 fled.
